The ternary layered cathode materials (LiNi1/3Co1/3Mn1/3O2) was synthesized by hydrothermal synthesis-high temperature solid phase method.The effects of different surfactants on the morphology,structure and electrochemical properties of the materials were discussed.The morphology and structure of the materials were characterized by XRD and SEM.The electrochemical properties of the materials were studied by means of CV,EIS,cycle and magnification tests.The experimental results showed that the sodium dodecylbenzene sulfonate (SDBS) was the best,and the nanoparticles with uniform morphology,good dispersion and spherical morphology were obtained.Under the condition of 2.5~4.6V and 0.5C,the initial discharge specific capacity reached 184.66 mAh/g,and the capacity retention rate after 100 cycles was 87.03%.This indicated that the prepared positive electrode materials LiNi1/3Co1/3Mn1/3O2 had good electrochemical properties.
